IMPROVEMENT IN GAS=REGULATORS.

Specification forming part of Letters Patent No. 158,255, dated December29, 1874; application filed October 12, 1874.

To all whom it may concern Be it known that we, EMANUEL DETWILER andGUSTAV FAJEN, of Milwaukee, in the county of Milwaukee, in the State ofWisconsin, have invented certain Improvements in Gas- Regulators, ofwhich the following is a specification Our invention has for its objectthe control of the How of gas, and is accomplished by a valve andapparatus for opening the same by a system of wires and arms, and awheel and screw for operating the wires.

Figure 1 is a sectional view of the invention Fig. 2, a view of thevalve and valve-seat; Fig. 3, a sectional view of the handle and screwwith which the apparatus is operated.

A is the casein which the valve is located; B, a shaft running downthrough the case, and to which an arm is attached which operates thevalve. 0 is a stuffing-box on this rod, which prevents the gas fromescaping around the rod through the partition in the case; D, the stepfor this shaft in the lower partition E, the valve-seat F, the valve; G,a pin standing on the top of the valve; H, a keeper at the end of thevalve, through which a bar, I, passes, and steadies the valve in place;K, an arm out from shaft B, and through the end of which pin G passes;L, another arm from shaft B, attached to spring M, which closes thevalve when the wires are slaoked; N, an arm on the top of shaft B,attached to arm Q, which, when the wire P is drawn, pulls this arm roundand opens the valve; Q, an arm secured to any permanent fastening by apin,

A R, another arm secured by pin B S, a raised bell-like piece secured tosomething permanent, into which screw T works on the top, and strikesonto; U, a movable arm attached to the side of the bell, and draws onwire V; WV, a wire which connects the arms Q and B, so that as the wireV is pulled all the wires draw together; X, the opening under valve Efor the gas to pass through; Y, the upper partition in the valve-case Z,the lower partition in the valve-case 5 A, bolt which holds arm Q inposition; B, bolt which holds arm B in position; 0, outlet for the gasfrom the valve-case 5 D, inlet for the gas to the valvecase.

This invention is a useful article for shutting off the gas andregulating the flow of gas whenever alight flow is needed. The machinecan be put up anywhere, and the handle T used at any point wherenecessary. To put on the gas, turn the screw T in, and that will presson arm U, and draw wire V, which will draw the other arms wires tillthey reach wire P, and that connected with arm 0, attached to arm N,will turn shaft B and open the valve as much as is wanted, in proportionto the turning of the screw T, and let gas into the center opening ofthe valve-case and out through the outlet 0. Whenever it is necessary toclose off the flow of gas, turn the handle T in an opposite direction,and the spring Mwill turn the shaft B and close the valve. One or moreregulators can be used whenever necessary to open or close more or lessburners. A

We claim as our invention 1. An improvement in gas-regulators,consisting of rod or shaft B, stuflingbox G, valveseat E, valve F, withpin G on the top of the valve, keeper H, with box I passing throughkeeper H, and spring M, combined and arranged substantially asdescribed.

2. The valve-operating shaft or rod B, in combination with arms Q andIt, bell S, screw T, arm U, and wires 1 W, and V, arranged substantiallyas set forth.
